Question

Could someone please help in explaining the error I get when executing following statement:
Error starting at line 1 in command:
`
CREATE OR REPLACE FORCE VIEW "PRODILMOWNER"."ZV_LPEUR_I" ("MANDT","BALANCETYPE", "BRANCH", "CURRENCY", "AMOUNT", "COUNTERPARTY", "COUNTERPARTY_PARENT", "AMOUNT_EUR","DESCRIPTION")

a.branch,
a.currency,
cast a.amount as number (25,2),
a.counterparty,
a.counterparty_parent,
a.mandt,
a.description,
(a.amount*
(SELECT c.midspot
FROM ZV_EXCHANGERATES c
WHERE c.currency =a.currency
AND c.valuedate =TO_CHAR(sysdate,'YYYY/MM/DD')
AND a.valuedate = TO_CHAR(sysdate,'DD-MMM-YY')
) ) AS cast amount_eur as number (25,2),
FROM ZT_LP a
Error at Command Line:1 Column:0
Error report:

Answer 1

You may have other errors, but the correct way to express a cast is:
cast(a.amount as number(25, 2)) as amount,
Note the parentheses and the column alias.

Answer 2

If you try to create view as following :
CREATE OR REPLACE FORCE VIEW "PRODILMOWNER"."ZV_LPEUR_I" ("MANDT","BALANCETYPE", "BRANCH", "CURRENCY", "AMOUNT", "COUNTERPARTY", "COUNTERPARTY_PARENT", "AMOUNT_EUR","DESCRIPTION")
AS
SELECT a.balancetype,
a.branch,
a.currency,
cast(a.amount as number(25, 2)) as amount, --cast a.amount as number (25,2),
a.counterparty,
a.counterparty_parent,
a.mandt,
a.description,
a.amount*
(SELECT cast(c.midspot as number(25, 2))
FROM ZV_EXCHANGERATES c
WHERE c.currency =a.currency
AND c.valuedate =TO_CHAR(sysdate,'YYYY/MM/DD')
AND a.valuedate = TO_CHAR(sysdate,'DD-MMM-YY')
) AS amount_eur -- cast amount_eur as number (25,2) --,
FROM ZT_LP a;
by removing parts right next to dashes(--), then no problem remains.
take casts in paranthesis
take second cast inside subselect
remove the comma , just before FROM clause
